The SABMB225 is a 2-channel supercapacitor auto-balancing PCB with an ALD910025SALI SAB MOSFET pre-installed and tested, designed to balance two series-connected supercapacitors with near-zero additional power dissipation. The board measures 0.6 in. by 1.0 in. and features an 8-lead SOIC footprint with terminal labels V+, A, B, C, and V-, and includes mounting holes. It operates within an industrial temperature range of -40°C to +85°C and is RoHS compliant. The ALD910025SALI device on the board is rated for a maximum reverse bias diode current of 80 mA per SAB MOSFET and supports cascading with other SABMBXX boards to balance larger supercapacitor stacks. Optional Schottky rectifiers can be added across each MOSFET to clamp transient surge currents.
ALD offers a line of Supercapacitor Auto Balancing Integrated Circuits (IC) as well as SAB and SABOVP (Over-Voltage Protection) Printed Circuit Boards (PCB). The SAB PCBs provide active continuous leakage current regulation and self-balancing of unlimited quantities of stacked series-connected supercapacitors. These products, when used in appropriately designed applications, dissipate near-zero leakage currents, practically eliminating extra power dissipation. Supercapacitors connected in series stacks can be balanced with various combinations of multiple cascaded SABMB or SABMBOVP packages.
